Kent,
The customer who owns that CI put those on himself. They are made of a dress-up automotive plastic/chrome trim. They are attached with a doubled-sided tape. They come in a "strip" with both ends tapered. He cut the strip in half to make 2 separate pieces. He then had to cut it to match the curve of the door. A coping saw would do the trick.
A couple things to consider...any water draining off the ends will leave a streak down the side of the tear. It will be more difficult to clean around & in between the strips, especially if you use a buffer. Also, because of the double stick tape, when you are installing them, you only have one shot at getting them right.
The recommended way to install them is to tape them into place with a good quality masking tape. When you are satisfied with the placement, use the tape to make a hinge above the strip. Practice flipping it up like you are removing the backing and flipping it down into place. When you are sure you can do it right, remove the backing and flip down into place.
